In enzymology a D-ribitol-5-phosphate cytidylyltransferase (EC 2.7.7.40) is an enzyme that catalyzes the chemical reactionCTP + D-ribitol 5-phosphate diphosphate + CDP-ribitolThus the two substrates of this enzyme are CTP and D-ribitol 5-phosphate whereas its two products are diphosphate and CDP-ribitol.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases).
